Minimizing moves and maximizing health will ensure you get the highest score possible! The dungeon you inhabit features a bounty of traps, enemies, and puzzles. You can move in any of the cardinal directions as long as there is a room there.\nYou can show your current inventory with I and if there is an item to interact with using the command U to use an item in your inventory. Using P will allow you see you current health and points. Finally you can show the map of the dungeon with M.\n\nEnter ‘B’ to begin and best of luck to you traveller!" << endl;
